3T MRI

New 3T 2015

The Siemens MAGNETOM Fit whole-body 3 Tesla MRI scanner is a short-bore magnet, with a 60 cm diameter with full clinical capabilities on the VE11 software platform.  The system contains 204 seamlessly integrated coil elements and 64 RF receiver channels, with the ability to scan the full body with a field of view of 50 cm and up to 181 cm in length.  The maximum gradient strength is 80 mT/m simultaneous on all 3 axes with a slew rate up to 200 T/m/s, and both active and passive noise reduction technology greatly reduces noise level compared to traditional systems.  The integrated Tim (Total Imaging Matrix) 4G technology provides unprecedented flexibility, accuracy, and speed, and is capable of reducing scan times by up to 50%.
